H4R expression increased in a rat model of lipopolysaccharide (LPS)-induced CNS inflammation. Knockdown of H4R in microglia HAPI cells enhanced the production of cytokines following LPS stimulation. Co-immunoprecipitation experiments further revealed an interaction between H4R and tumor necrosis factor receptor-associated factor 6 (TRAF6) in microglia, which was verified both in vivo and in vitro. | H4 Receptor Inhibits Lipopolysaccharide-induced NF-κB Activation by Interacting with Tumor Necrosis Factor Receptor-Associated Factor 6.
